Summary

[edit]
Description
English: Primary follicle homeostasis. The video begins with an empty BTU. As time progresses, lymphocytes enter the tissue. Colors: naive B-cells (red) and naive CD4/8. Driven by chemotaxis, naive B-cells migrate to the FDC populated follicle in response to CXCL13, while memory B-cells and T-cells remain in the FRC populated extrafollicular region in response to CCL21/19. Cells remain in the BTU for ∼12–24 hours, at which point they change their chemotaxis preference to the exit chemokine S1P and actively leave via efferent lymphatics at the bottom of the tissue (exiting naive B-cells shown in yellow).
